How are npn and pnp types of transistors different?
Options
- AIn the number of layers they have
- BIn the type of charge carriers they use
- CIn their ability to convert light energy
- DIn the arrangement of their layers
Correct answer
D. In the arrangement of their layers
Step-by-step solution
npn and pnp types of transistors differ in the arrangement of their layers, with one having two layers of n-type semiconductor and one layer of p-type semiconductor, while the other has two layers of p-type semiconductor and one layer of n-type semiconductor.
